Because there are frequent failures in the connection method which uses crosshead intermediate axle shaft to join the relevant oart in the axis system of transmission system coupling this article suggests to use copper sliding pieces type transmission to increase the life of the middle axle system in transmission 摘要針對(duì)主傳動(dòng)中間軸系統(tǒng)采用十字頭聯(lián)軸器與相關(guān)件連接方式,故障較多,改進(jìn)為銅滑塊式傳動(dòng),提高了主傳動(dòng)中間軸系統(tǒng)的壽命。
